Recombinant DNA is the general name for a piece of DNA that has been created by the combination of at least two strands. Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera.
Recombinant DNA is formed by using a restriction enzyme that cuts the double strand at a particular point. The same enzyme is used to cut a second piece of DNA.When the fragments are mixed together, the complementary ends of each strand will bind with those of the other, forming a recombinant DNA molecule.ecombinant DNA is formed by using a restriction enzyme that cuts the double strand at a particular point.
